The UCC283−3/−5/−ADJ family of positive linear  
+
series pass voltage regulators are tailored for  
low-drop-out applications where low quiescent  
power is important. Fabricated with a BiCMOS  
technology ideally suited for low input-to-output  
differential applications, the UCC283−5 passes  
3 A while requiring only 0.45 V of typical input  
voltage headroom (ensured 0.6-V dropout).  
1
These regulators include reverse voltage sensing that prevents current in the reverse direction. Quiescent  
current is always less than 650 µA. These devices have been internally compensated in such a way that the  
need for a minimum output capacitor has been eliminated.  
UCC283−3 and UCC283−5 versions are in 3-lead packages and have preset outputs at 3.3 V and 5.0 V  
respectively. The output voltage is regulated to 1.5% at room temperature. The UCC283−ADJ version, in a  
5-lead package, regulates the output voltage programmed by an external resistor ratio.  
Short-circuit current is internally limited. The device responds to a sustained overcurrent condition by turning  
off after a t  
time delay. The device then stays off for a period, t  
, that is 32 times the t  
delay. The device  
ON  
OFF  
ON  
then begins pulsing on and off at the t /(t +t  
) duty cycle of 3%. This drastically reduces the power  
ON ON OFF  
dissipation during short-circuit and means heat sinks need only accommodate normal operation. On the  
3-leaded versions of the device t  
is fixed at 750 µs, on the adjustable 5-leaded versions an external capacitor  
ON  
sets the on time. The off time is always 32 × t . The external timing control pin, CT, on the 5-leaded versions  
ON  
also serves as a shutdown input when pulled low.  
Internal power dissipation is further controlled with thermal overload protection circuitry. Thermal shutdown  
occurs if the junction temperature exceeds 165°C. The chip remains off until the temperature has dropped 20°C.  
The UCC283 series is specified for operation over the industrial range of −40°C to 85°C, and the UCC383 series  
is specified from 0°C to 70°C. These devices are available in 3- and 5-pin TO−220 and TO−263 power packages.

CT: Short-circuit timing capacitor and shutdown input for the UCC283−ADJ version. Pulling CT below 0.25 V  
turns off the regulator and places it in a low quiescent-current mode. A timing capacitor, C, from CT to GND  
programs the duration of the pulsed short-circuit on-time. On-time, t , is approximately given by:

GND: Reference ground.  
VIN: Input voltage, This pin must be bypassed with a low ESL/ESR 1-µF or larger capacitor to GND. VIN can  
range from (VOUT + V  
) to 9 V. If VIN is reduced to zero while VOUT is held high, the reverse leakage  
DROPOUT  
from VOUT to VIN is less than 75µA.  
VOUT: Regulated output voltage. A bypass capacitor is not required at VOUT, but may be desired for good  
transient response. The bypass capacitor must not exceed a maximum value in order to insure the regulator  
can start.  
APPLICATION INFORMATION  
overview  
The UCC383 family of low dropout linear (LDO) regulators provide a regulated output voltage for applications  
with up to 3 A of load current. The regulators feature a low dropout voltage and short-circuit protection, making  
their use ideal for demanding high-current applications requiring fault protection.  
short-circuit-protection  
The UCC383 provides unique short-circuit protection circuitry that reduces power dissipation during a fault.  
When an overload situation is detected, the device enters a pulsed mode of operation at 3% duty cycle reducing  
the heat sink requirements during a fault. The UCC383 has two current thresholds that determine its behavior  
during a fault as shown in Figure 1. When the regulator current exceeds the overcurrent threshold for a period  
longer than t , the UCC383 shuts off for a period (t  
) which is 32 × t . During an overload, the regulator  
ON  
OFF  
ON  
actively limits the maximum current to the peak current limit value. The peak current limit is nominally 3 A  
greater than the overcurrent threshold. The regulator continues in pulsed mode until the fault is cleared as  
illustrated in Figure 1.

Figure 1. UCC383 Short-Circuit Timing  
A capacitive load on the regulator’s output appears as a short-circuit during start-up. If the capacitance is too  
large, the output voltage does not come into regulation during the initial t period and the UCC383 enters  
ON  
pulsed mode operation. The peak current limit, t  
period, and load characteristics determine the maximum  
ON  
value of output capacitor that can be charged. For a constant current load the maximum output capacitance is

dropout performance  
Referring to the Block Diagram, the dropout voltage of the UCC383 is equal to the minimum voltage drop (V  
IN  
to V  
) across the N-channel MOSFET. The dropout voltage is dependent on operating conditions such as  
OUT  
load current, input and load voltages, as well as temperature. The UCC383 achieves a low Rds(on) through the  
use of an internal charge-pump (V ) that drives the MOSFET gate. Figure 2 depicts typical dropout voltages  
PUMP  
versus load current for the 3.3-V and 5-V versions of the part, as well as the adjustable version programmed  
to 3.0 V.  
Figure 3 depicts the typical dropout performance of the adjustable version with various output voltages and load  
currents.  
Operating temperatures also affect the Rds(on) and dropout voltage of the UCC383. Figure 4 graphs the typical  
dropout for the 3.3-V and 5-V versions with a 3-A load over temperature.

The maximum programmed output voltage is constrained by the 9-V absolute rating of the IC (this includes the  
charge pump voltage) and its ability to enhance the N-channel MOSFET. Unless the load current is below the  
3-A rating of the device, output voltages above 7 V are not recommended. The minimum output voltage can  
be programmed down to 1.25 V. However, the input voltage must always be greater than the UVLO of the part.  
The adjustable version includes a shutdown feature, limiting quiescent current to 40 µA typical. The UCC383  
is shut down by pulling the CT pin to below 0.25 V. As shown in Figure 5, a small logic level MOSFET or BJT  
transistor in parallel with the timing capacitor can be driven with a digital signal, putting the device in shutdown.  
If the CT pin is not pulled low, the IC internally pulls up the pin enabling the regulator. The CT pin should not  
be forced high, as this interferes with the short-circuit-protection feature. Selection of the timing capacitor is  
explained in Short-Circuit-Protection.  
The adjustable version can be used in applications requiring remote voltage sensing (i.e. monitoring a voltage  
other than or not directly tied to the VOUT pin). This is possible since the inverting input of the error-voltage  
amplifier (see Block Diagram) is brought out to the ADJ pin.

APPLICATION INFORMATION  
thermal design  
The Package Information section of the Power Supply Control Products Data Book, Volume 3 (Literature  
No. SLUD003) contains reference material for the thermal ratings of various packages. The section also  
includes an excellent article Thermal Characteristics of Surface Mount Packages, that is the basis of the  
following discussion.  
Thermal design for the UCC383 family of linear regulators includes two modes of operation, normal and pulsed  
mode. In normal operation, the linear regulator and heat sink must dissipate power equal to the maximum  
forward voltage drop multiplied by the maximum load current. Assuming a constant current load, the expected  
heat rise at the regulator’s junction can be calculated as follows:  
°C  
  ǒq caǓ  
) q  
t
(q) + P  
RISE  
DISS  
jc  
(5)  
Where theta, (θ) is thermal resistance and P  
is the power dissipated. The thermal resistance of both the  
DISS  
TO−220 and TO−263 packages (junction to case) is 3°C per Watt. In order to prevent the regulator from going  
into thermal shutdown, the case to ambient theta must keep the junction temperature below 150°C. If the LDO  
is mounted on a 5-square inch pad of 1-ounce copper, for example, the thermal resistance from junction to  
ambient becomes 60°C per Watt. If a lower thermal resistance is required by the application, the device heat  
sinking would need to be improved.  
When the UCC383 regulator is in pulsed mode due to an overload or short-circuit in the application, the  
maximum average power dissipation is calculated as follows:  
t
ON  
+ ǒVIN  
Ǔ
  I  
P
* V  
 
Watts  
PULSE(avg)  
OUT  
CL  
33   t  
ON  
(6)  
As seen in Equation 6, the average power during a fault is reduced dramatically by the duty cycle, allowing the  
heat sink to be sized for normal operation. Although the peak power in the regulator during the t period can  
ON  
be significant, the thermal mass of the package generally keeps the junction temperature from rising unless the  
period is increased to tens of milliseconds.  
t
ON  
ripple rejection  
Even though the UCC383 family of linear regulators are not optimized for fast transient applications (Refer to  
the UC182 Fast LDO Linear Regulator), they do offer significant power supply rejection at lower frequencies.  
Figure 6 depicts ripple rejection performance in a typical application. The performance can be improved with  
additional filtering.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which  
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such  
components to meet such requirements.
